That's a great suggestion.

I've been through everything trying to get a decent HiDPI experience, I'm running Opera beta and it all just works perfectly.

I'm running Debian Testing/Jessie and I've found that the Cinnamon Desktop Environment is the best for me, I've tried them all (trying to get the best results for HiDPI) and it is the one I'm most happy with.
